Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.
As shown in fig. 1, a protection device for a storage tank comprises a storage tank body 1 and a U-shaped pipe 2, wherein an outlet end of the storage tank body 1 is communicated with a discharge pipe, one end of the discharge pipe is communicated with the top of the U-shaped pipe 2, and the top of one end of the U-shaped pipe 2 is communicated with an inclined pipe 3;
the other end of the storage tank body 1 is provided with an air outlet pipe 9, one end of the air outlet pipe 9 is communicated with a three-way pipe 10, one end of the three-way pipe 10 is communicated with an air inlet pipe 4, the other end of the air inlet pipe 4 is communicated with an air inlet of the storage tank body 1, and the air inlet pipe 4 which is far away from the storage tank body 1 is sequentially provided with an air release pipe 11, a first valve 8 and a pressure gauge 5;
the other end of the three-way pipe 10 is communicated with an air supply pipe 7, a second valve 6 is arranged on the air supply pipe 7, the other end of the air supply pipe 7 is communicated with the air supply pipe 4, and the communication position of the other end of the air supply pipe 7 and the air supply pipe 4 is positioned between the first valve 8 and the pressure gauge 5.
And a third valve is arranged on the discharge pipe.
The storage tank body 1 is a horizontal storage tank.
The fourth valve 12 is installed on the air release pipe 11.
The diameters of the air leakage pipe 11, the air supply pipe 7 and the air delivery pipe 4 are increased in sequence.
The other end of the inclined pipe 3 is arranged obliquely downwards relative to the side wall of the U-shaped pipe 2.
The working principle is as follows: the device utilizes the matching of the discharge pipe, the U-shaped pipe 2 and the inclined pipe 3 to ensure that redundant materials are stored in the U-shaped pipe 2 when the third valve is closed due to the limitation of the U-shaped pipe 2 when the materials are unloaded, so that the leakage condition of the materials when the unloading is stopped can be reduced (mainly, when the material is unloaded, the third valve is opened, the materials flow out of the storage tank body 1 through the discharge pipe, the U-shaped pipe 2 and the inclined pipe 3, when the unloading is finished, the third valve is closed, the materials in the discharge pipe are limited due to the shape of the U-shaped pipe 2, and the leakage condition of the materials when the unloading is stopped is reduced);
in addition, the gas outlet pipe 9, the three-way pipe 10, the gas pipe 4, the gas supplementing pipe 7, the gas release pipe 11, the pressure gauge 8, the second valve 6, the first valve 8 and the fourth valve 12 are mutually matched, so that inert gas can be properly input into the storage tank body 1 according to the actual production situation, and the situation that the inert gas is wasted or the inert gas is not filled sufficiently is avoided (firstly, the first valve 8 is opened, the second valve 6 and the fourth valve 12 are closed and opened, then, an external gas pump is started, the gas passes through the three-way pipe 10 through the gas outlet pipe 9 and enters the gas pipe 4 to enter the storage tank body 1, and the gas entering the storage tank body 1 from the gas pipe 4 is monitored by the pressure gauge 5 in the conveying process, once the pressure of the pressure gauge 5 is too high, the fourth valve 12 on the gas release pipe 11 is opened at the moment, and the first valve 8 and the second valve 6 are closed, so that part of the gas is discharged through the gas leakage pipe 11 until the pressure gauge reaches a predetermined value; once the pressure of the pressure gauge 5 is too low, the second valve 6 is opened, the first valve 8 and the fourth valve 12 are closed, at the moment, gas enters the gas pipe 4 through the gas outlet pipe 9 and the gas supplementing pipe 7, and then the pointer of the pressure gauge 5 begins to deflect until the pressure of the pressure gauge 5 reaches a preset value).
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the claimed invention.
